Due to the recent loss in water pressure, the City of Jackson Water/Sewer Utilities Division has issued a precautionary boil water advisory until further notice for the following area:

Surface Water Customers with zip codes of 39204, 39212, and 39209

Byram Surface Water Customers with zip codes of 39272

Jackson State University 1400 JR Lynch Street, 39203

20,000 customers are under the advisory, city officials said.

The city will continue to handout water at the Metrocenter from 8 a.m. to noon on Sunday.

This comes after a 48-inch water main line was replaced and repaired during a major project on Forest Avenue that started around 3 p.m. Friday and was complete around 5 p.m. Saturday.

The line, which supplies water to south and west Jackson and areas of Bryam, had been spewing water for about three months.

The city shut off the water to that area, which has left much of the city with low or no water pressure, but Jackson Mayor Tony Yarber tweeted Saturday Morning that pressure appears to be decent across the city.

"While we are ahead of schedule, what we don’t want to do is raise expectations. We’re still looking at 3 p.m. Sunday (to turn the water back on) because we need to see the results from those tests," Yarber said.

A boil-water alert will be issued and will remain in effect for at least 48 hours, city officials said.

Yarber said the line, which is made of pre-stress concrete, was installed in 1990. When crews dug up the line, there were about 3 inches of Yazoo clay.

"It was thick and it was messy," Yarber said.

The city has given out more than 15,000 cases of water since Friday and delivered about 2,000 cases to those who are disabled, Yarber said.

"I cannot reassure Jackson residents that this will not happen again," Yarber said.

But the city, like many others around the country, is working to repair and restore an aging infrastructure, Yarber said.
